PARAMETERS

node

Handle to a device node in the snapshot of kernel device tree.

ph

PROM handle

prom_prop

Handle to a PROM property.

prop_data

Address of a pointer.

DESCRIPTION

The di_prom_prop_next() function obtains a handle to the next property on the PROM property list associated with node. If prom_prop is DI_PROM_PROP_NIL, the first property associated with node is returned.

The di_prom_prop_name() function returns the name of the prom_prop property.

The di_prom_prop_data() function returns the value of the prom_prop property. The return value is a non-negative integer specifying the size in number of bytes in prop_data.

All memory allocated by these functions is managed by the library and must not be freed by the caller.

RETURN VALUES

The di_prom_prop_data() function returns the number of bytes in prop_data and prop_data is updated to point to a byte array containing the property value. If 0 is returned, the property is a boolean property and the existence of this
property indicates the value is true.

The di_prom_prop_name() function returns a pointer to a string that contains the name of prom_prop.

The di_prom_prop_next() function returns a handle to the next PROM property. DI_PROM_PROP_NIL is returned if no additional properties exist.
